Illustrated Guide to the world of Spira (FFX and FFX-2)/Lost Cities/City Ruins

All large ruins share Zanarkand's distinctive architectural style of tall round towers with pointed cones, with a band of decorative runes around each cone. The tower colors resemble terracotta and the decorations are usually blue/green. Windows tend to be circular. Smaller ruins, like broken down temples and dungeons do not have Zanarkand's distinctive style.
